Has anyone upgraded the HD on the 2010 13"?

When I bought the 13" MBA with 128 GB I figured that there would be upgrades to bigger capacity SSD's within six months or so. I have heard of some fairly expensive upgrade options but haven't seen any posts from people who have upgraded. My drive is almost at capacity and I am now in need of that upgrade.

At this point I am thinking that if there aren't better alternatives i might just sell what I have and get the new 2011 MBA when it comes out in a few days with a bigger HD.

Thanks for the feedback. I noticed that OWC has lowered the price of their 360 GB model to $779. Still very high but a definite improvement. I look forward to see what the prices on the new 13" with bigger drives will be when they come out later this week, hopefully.
